帝曰∶阴盛生内寒奈何？曰∶厥气上逆，寒气积于胸中而不散。不散则温气去，寒独留则血凝
。血凝则脉不通，其脉盛大以涩，故中寒。按诸病上下，所出水液澄澈清冷， 瘕 疝，坚痞腹满
急痛，下利清白，食已不饥，吐利腥秽，屈伸不便，厥逆禁固，皆属于寒。盖痼冷之证，乃真阳耗
散，脾胃亏伤，又啖生冷难化之物。或受风寒阴湿，经年累月，日久乃成。则脾胃因而渍积，脏腑
致成虚寒。及有外邪触犯，内外邪相感，忽然而作手足厥冷、战栗憎寒，呕吐涎沫，脐腹绞痛，或常得大便洞泄，小便
频数，饮食不化，咳嗽， 疝等证。其脉沉而迟，治宜温养脾胃，补益气血，助阳固本。

黄帝问道：阴气偏盛为什么会引起内寒？岐伯回答说：厥逆之气向上冲逆，寒气积聚在胸中而不能消散。寒气不散则温煦之气离去，只有寒气独留，就会导致血液凝滞。血液凝滞则脉道不通，脉象表现为盛大而涩，所以出现中寒的症状。观察各种疾病，凡是上下排出的水液清澈寒冷，以及瘕疝、坚硬痞块、腹部胀满急痛，下利清稀白色，进食后不觉饥饿，呕吐物带有腥秽气味，身体屈伸不便，四肢厥冷且拘谨僵硬，这些症状都属于寒证。大抵痼冷之证，是由于真阳耗散，脾胃受损，又食用生冷难消化的食物。或者感受风寒阴湿之气，经年累月，日久便形成此病。于是脾胃因此积滞，脏腑导致虚寒。如果再有外邪触犯，内外邪气相互感应，突然发作出四肢厥冷、战栗怕冷，呕吐涎沫，脐腹绞痛，或者经常大便洞泄，小便频数，饮食不消化，咳嗽，疝气等症状。其脉象沉而迟，治疗应当温养脾胃，补益气血，助阳固本。
主方为理中汤（Cinnamon Twig and Ginger Decoction），药用：人参（Ginseng Radix）、白术（Atractylodis Macrocephalae Rhizoma）、干姜（Zingiberis Rhizoma）、炙甘草（Glycyrrhizae Radix et Rhizoma Preparata）。
若寒邪极重，可加附子（Aconiti Lateralis Radix Praeparata）或川乌（Aconiti Radix）。用生姜七片，黑枣二枚，加水煎服。若病情未安，可加丁香（Caryophylli Flos）、木香（Aucklandiae Radix）、砂仁（Amomi Fructus）、白豆蔻（Cardamomi Fructus）、胡椒（Piperis Longi Fructus）、肉桂（Cinnamomi Cortex）、茴香（Foeniculi Fructus）、沉香（Aquilariae Lignum Resinatum）、荜茇（Piperis Kadsurae Fructus）等药，根据病情轻重选用，另研成细末调入服用。以上药物皆为温暖脾胃、温煦脏腑之品，随证加减使用。
若气血虚弱，可用十全大补丸（Shiquan Dabu Pill）；若下元冷惫（肾阳不足导致的寒冷疲乏），可用桂附八味丸（Guifu Bawei Pill）（这两方见补益篇）。

The Yellow Emperor asked: Why does an excess of Yin cause internal cold? The answer is: Jue Qi (rebellious Qi) moves upward, causing cold Qi to accumulate in the chest without dispersing. If it does not disperse, the warming Qi departs, leaving only cold Qi, which causes blood coagulation. Blood coagulation leads to obstruction of the vessels; the pulse appears large yet choppy, thus indicating Zhong Han (Cold invading the Middle Jiao). Observing various diseases, any fluid discharged from above or below that is clear and cold, as well as Zha Shan (abdominal masses and hernia), hard and fixed fullness with abdominal distension and acute pain, diarrhea with clear white stool, lack of hunger after eating, vomiting with fishy or foul odor, difficulty in flexing and extending the limbs, Jue Ni (cold extremities) with stiffness and immobility, all belong to Cold syndromes. Generally, Gu Leng (stubborn cold) arises from the depletion and dispersion of True Yang, damage to the Spleen and Stomach, and the consumption of raw, cold, and indigestible foods. Alternatively, it results from exposure to Wind-Cold and Yin-Dampness over years, eventually forming this condition. Consequently, the Spleen and Stomach become stagnant, and the Zang-Fu organs develop deficiency-cold. When external pathogens invade, internal and external evils interact, suddenly causing symptoms such as cold extremities, shivering and aversion to cold, vomiting of saliva and foam, colicky pain in the umbilical and abdominal regions, frequent loose stools, frequent urination, undigested food in stool, cough, and Shan (hernia). The pulse is deep and slow. Treatment should focus on warming and nourishing the Spleen and Stomach, tonifying Qi and Blood, assisting Yang, and consolidating the Root.
The main formula is Lizhong Tang (Cinnamon Twig and Ginger Decoction), consisting of: Renshen (Ginseng Radix), Baizhu (Atractylodis Macrocephalae Rhizoma), Ganjiang (Zingiberis Rhizoma), and Zhigancao (Glycyrrhizae Radix et Rhizoma Preparata).
If the cold is severe, add Fuzi (Aconiti Lateralis Radix Praeparata) or Chuanwu (Aconiti Radix). Decoct with seven slices of Shengjiang (Zingiberis Rhizoma Recens) and two black dates (Heizao, Ziziphi Jujubae Fructus Nigricans) in water. If the condition remains unrelieved, add Dingxiang (Caryophylli Flos), Muxiang (Aucklandiae Radix), Sharen (Amomi Fructus), Baidoukou (Cardamomi Fructus), Hujiao (Piperis Longi Fructus), Rougui (Cinnamomi Cortex), Huixiang (Foeniculi Fructus), Chenxiang (Aquilariae Lignum Resinatum), and Biba (Piperis Kadsurae Fructus), selected according to severity, ground into fine powder, and mixed into the decoction for ingestion. All the above herbs are agents that warm the Spleen and Stomach and heat the Zang-Fu organs; they should be added or subtracted according to the syndrome.
For Qi and Blood deficiency, use Shiquan Dabu Wan (Ten Ingredients Great Tonifying Pill); for cold exhaustion of the Lower Yuan (Kidney Yang deficiency leading to cold and fatigue), use Guifu Bawei Wan (Cinnamon and Aconite Eight-Ingredient Pill) (see both formulas under Tonification).
Dudou Formula (Treats stubborn cold accumulation in the abdomen with miraculous effect. Also benefits the Dantian and Shenque acupoints, aiding fertility. Suitable for men and women. Contraindicated during pregnancy.)

Grind the above into powder, mix with Ai Mian (moxa cotton), place inside a cloth pouch sewn securely with thread to prevent shifting. Wrap tightly around the lower abdomen. Initially wear for one night, then remove the next day. Gradually extend to wearing for two nights before removing, then five nights before removing, until it can be worn continuously.

Another Prescription: Treats deficiency-cold of the Lower Yuan.
Take Hujiao (Piperis Longi Fructus) and Poguzhi (Psoraleae Fructus, stir-fried), grind into powder, form pills with honey, and take with wine on an empty stomach.
